[PD-dev] building Pd from git with asio support: portaudio can't find asio headers

definitely!

congrats! :-) I've just been there in June for next_generation.

awesome!

unfortunately, with 'make install' I always end up with a static build (a large pd.exe instead of large pd.dll + small pd.exe). the build works with all the externals in 'extra' but not with other externals so it's useless for deployment :-(. the missing pd.dll is the biggest obstacle and I'm trying to figure out how to solve this. I have to say I still know very little about autotools and makefiles in general, but I'm digging into it.

so far I recognized four major things to fix:

1) create pd.dll
2) fix asio search paths for portaudio
3) installing missing files to bin (wish85.exe and some dlls). I discovered that they are contained in msw/pdprototype.tgz but they don't get installed for some reason.
4) fix the install folder structure (as it doesn't work as it is, I have to move things around) and make a configure option for a Windows style install, following the folder structure of Miller's Windows build.
 
but let's do it after the Pd release :-)

I can't get to it to until later, but let's stay in sync on this. In the mean time, you could propose your builds to Miller until we can figure out the character issues.
 
I have a new job (ZKM) and a Windows 10 install, so my plan is fix the autootools build issues on Windows. I'm sure I'll need your knowledge as you have gotten the farthest with this so far.

Hi Dan,

I know, there is more urgent stuff going on right now, but in case I forget:

I tried to compile Pd from git with asio support. My system is msys2 on Windows 7. When compiling portaudio, gcc can't find the necessary ASIO headers (which are in asio/ASIOSDK2). I tried to add the directory via configure (--includedir, CFLAGS, CPPFLAGS, ...) without success.

copying the following header files from ASIOSDK2 to /portaudio/portaudio/include did the trick:

asio.h
asiodrivers.h
asiodrvr.h
asiosys.h
combase.h
ginclude.h
iasiodrv.h
pc/asiolist.h (yes, asiolist.h has to be in a folder 'pc')

also, ASIO seems to link dynamically to libstdc++-6.dll from msys64/mingw32/bin. for me, there was an interference with another version of libstdc++-6.dll somewhere in my system. I also had this problem with openFrameworks. I think it's good to either link statically or to copy libstdc++-6.dll into Pd's bin folder. The latter is my personal solution for now. For OF, I always put it into the export folder so it gets copied automatically everytime I compile a new app. I can remember that other people had this problem with OF so I can imagine it could also be a problem with Pd.
